They're the new new kids on the boy band block. With their synchronized dance moves, slick costumes, and squeal-worthy good looks, it's no surprise One Direction is the boy band du jour.
The fivesome – Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson – were originally solo contestants for the U.K.'s X Factor, and it wasn't until judge Nicole Scherzinger suggested that they team up was One Direction born. They lost the competition – but Simon Cowell promptly signed them to his Syco record label. Following a well-received performance on Saturday Night Live, and drawing nearly 15,000 fans to their Today show appearance, the new British invasion are preparing for their headlining U.S. summer tour.
